This work proposes a DSP technique to mitigate the interference-induced spurious tones coupled to the digitally controlled oscillator (DCO) of a digital phase locked loop (DPLL). We leverage the digitized phase information at the time-to-digital converter (TDC) output, and formulate an adaptive algorithm to identify the interference pattern from any electrical or magnetic coupling path, and inject...
Electroencephalogram (EEG) signals are often contaminated with various artifacts, especially electrooculogram (EOG) or ocular artifacts that cannot be avoided consciously and largely degrade the clinical interpretation of the signals. This paper presents a study on adaptive noise cancellation (ANC) based on adapüve neuro-fuzzy inference system (ANFIS) for EOG artifacts removal, especially when time...
Some wideband wireless links such as unmanned aerial vehicle (UAV) and satellite links have much wider bandwidth than that of high power natural or artificial interference. An idea of adaptive narrow band interference (NBI) cancellation based on different algorithms and structures aiming at wideband wireless links where bandwidth of interference is relatively narrow is posed here. All these theoretically...
